Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. strontium iodide. (zV�cߌ�ա. BaS b. FeCl3 c. PbI4 d. SrBr2 Nomenclature, a collection of rules for naming things, is important in science and in many other situations.This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO 3, and N 2 O 4.The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing … Boundless Learning Most cations and anions can combine to form solid compounds that are usually known as salts. Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. h��U�nA��>�z_FB�l��H�D���8�=�[3��=���� ���յ�Z��J�dD�V� �V��4d��(�OI�y#?�M�b�?�����})?��y9?����l`qq�n6M7�W}�}$��ل����|>�Cs+b�����*� Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. So it is Fe3+. An ionic compound is named first by its cation and then by its anion. Formulas and Names for Ionic Compounds 1. Binary Ionic Compounds. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. Name: _____ Per: _____ Directions: First quickly scan the worksheet and circle any metals (as a symbol or as a name) that is a transition metal. CC BY-SA. The anion is named by taking the elemental name, removing the ending, and adding “ide.” For example, F-1 is called fluoride, for the elemental name, fluorine. ,�$-ځ$�l��㾖����yH(O������/� `� Use both the Stock and common systems, where appropriate. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. b) Calcium fluoride. Positive to positive and negative to negative ionic bonds do not occur. BaBr 2. 780 0 obj <>/Filter/FlateDecode/ID[]/Index[769 20]/Info 768 0 R/Length 76/Prev 1397859/Root 770 0 R/Size 789/Type/XRef/W[1 3 1]>>stream CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound The Roman numerals in fact show the oxidation number, but in simple ionic compounds this will always be the same as the metal’s ionic charge. This is a binary ionic compound. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. The polyatomic ion name stays the same. Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. Its older name is cupric chloride. To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Answer to Give each ionic compound an appropriate name. Writing names and formulas for ionic compounds. The net charge of an ionic compound must be zero. Give the name from the formula or the formula from the name for each of the following hydrated ionic compounds.BeCl2 • 2H2O. Think About It Make sure that the prefixes match the subscripts in the molecular Naming Ionic Compounds – Answer Key Give the name of the following ionic compounds: Name 1) Na 2CO 3 sodium carbonate 2) NaOH sodium hydroxide 3) MgBr 2 magnesium bromide 4) KCl potassium chloride 5) FeCl 2 iron (II) chloride 6) FeCl 3 iron (III) chloride 7) Zn(OH) 2 zinc hydroxide 8) Be 2SO 4 beryllium sulfate 9) CrF %%EOF Part 1: Binary Ionic Compounds Give the formula and name for the ionic compound formed between each of these metals with each of these nonmetals: Metals: sodium, magnesium, aluminum e) Strontium oxide. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. 9. 4. Name the following ionic compounds that contain polyatomic ions.
